Introduction to Groundwater Modeling : Finite Difference and Finite Element Methods
The dramatic advances in the efficiency of digital computers during the past decade have provided hydrologists with a powerful tool for numerical modeling of groundwater systems. Introduction to Groundwater Modeling presents a broad, comprehensive overview of the fundamental concepts and applications of computerized groundwater modeling. The book covers both finite difference and finite element methods and includes practical sample programs that demonstrate theoretical points described in the text. Each chapter is followed by problems, notes, and references to additional information. This volume will be indispensable to students in introductory groundwater modeling courses as well as to groundwater professionals wishing to gain a complete introduction to this vital subject.

Reviews of the Casebound Edition "It can be readily understood by all newcomers to numerical methods requiring only basic mathematical techniques...Short FORTRAN-computer programs for almost every problem...is a great advantage to the book...This book is as good as a complete and very detailed university course." -Journal of Geophysics "Very timely...The authors have succeeded in avoiding complex formulated expressions without losing mathematical consistency...This introduced textbook..will be very useful in the development of collegehydrogeology courses." -Groundwater Modeling Newsletter "A clear, concise little volume on a subject that has needed for such a treatment. It provides the best introduction to date on the most important tool of groundwater hydrology, the computer model." -Choice
